没有执行路由的快速装饰器类

如何解决没有执行路由的快速装饰器类

我一直在为快速控制器编写自定义装饰器。装饰器类没有被执行。我检查了 bundle.js 和装饰器代码被捆绑在 bundle.js 中

@controller("/api/v1/portfolios")
 class PortfolioController {
  @get("")
  async getPortfolios(req: Request,res: Response) {
    const portfolios = await Portfolio.find({});
    return res.json(portfolios);
  }}

我在 app.js 中导入了这个

const server = express();
import("./controllers/portfolios");
server.use(AppRouter.getInstance());

路由器是一个单例对象。

export class AppRouter {
  private static instance: express.Router;
  static getInstance(): express.Router {
    if (!AppRouter.instance) {
      AppRouter.instance = express.Router();
    }
    return AppRouter.instance;
  }
}

这是控制器装饰器

export function controller(routePrefix: string) {
  return function (target: Function) {
    const router = AppRouter.getInstance();
    for (let key in target.prototype) {
      const routeHandler = target.prototype[key]; //getLogin
      const path = Reflect.getMetadata(
        MetadataKeys.Path,target.prototype,key
      );
      const method: Methods = Reflect.getMetadata(
        MetadataKeys.Method,key
      );
      const middlewares =
        Reflect.getMetadata(MetadataKeys.Middleware,key) ||
        [];
      if (path) {
        router[method](
          `${routePrefix}${path}`,...middlewares,//   validator,routeHandler
        );
      }
    }
  };
}

这是 webpack.config.json

const path = require("path");
const { CleanWebpackPlugin } = require("clean-webpack-plugin");
const nodeWebExternals = require("webpack-node-externals");

module.exports = {
  entry: ["regenerator-runtime/runtime","./src/index.ts"],mode: "development",target: "node",output: {
    filename: "bundle.js",path: path.join(__dirname,"dist"),},module: {
    rules: [{ test: /\.ts$/,loader: "ts-loader",exclude: /node_modules/ }],resolve: {
    extensions: [".ts",".js",".json"],modules: [path.resolve(__dirname,"./src"),"node_modules"],externals: [nodeWebExternals()],plugins: [new CleanWebpackPlugin()],};

我收到此错误：

Cannot GET /api/v1/blogs
